Question

Aarushi spends $Rs.x$ daily and saves $Rs.y$ per week. How much money she saves in $x{y}^2$ weeks?

Answer 1

We have Money spent daily $=Rs.x$

Money saved per week $=Rs.y$

and Number of weeks $=x{y}^2$

As, the money spent per week $=7\times x=Rs.7x$

Money spent in $x{y}^2=7x\times \left(x{y}^2\right)=7x^2{y}^2$

Money saved in $x{y}^2$ week $=y\times x{y}^2=x{y}^3$
